Description

Pva-Tegda Copolymer CAS NO 143114-02-7 is a specialized synthetic polymer formed from the copolymerization of polyvinyl alcohol (PVA) and triethylene glycol diacrylate (TEGDA). This engineered material is valued for its unique balance of film-forming properties, crosslinkable functionality, and biocompatibility, making it a versatile component in advanced formulations. It is primarily sought after by manufacturers in the pharmaceutical, adhesive, and specialty coating industries for developing controlled-release systems, pressure-sensitive adhesives, and functional polymer matrices.

Application

• Pharmaceutical Excipient: Used as a film-forming agent and binder in tablet coatings and controlled-release drug delivery systems.
• Pressure-Sensitive Adhesives (PSAs): Serves as a key component in medical tapes, transdermal patches, and label adhesives due to its tunable tack and adhesion properties.
• Specialty Coatings: Employed in the formulation of protective and functional coatings for textiles, paper, and industrial surfaces.
• Hydrogel Formulations: Acts as a crosslinkable polymer network for creating hydrogels used in wound care, agriculture, and personal care products.
• Encapsulation Matrix: Utilized for the microencapsulation of flavors, fragrances, and active ingredients in food and agrochemical applications.
• Biomedical Materials: Investigated for use in tissue engineering scaffolds and bio-inks for 3D printing due to its biocompatible nature.

Quality Control

Our Pva-Tegda Copolymer is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure consistency in molecular weight distribution, degree of substitution, and residual monomer content. We provide Certificates of Analysis (COA) with key parameters, and our production can be aligned with cGMP guidelines for pharmaceutical applications. Specifications are designed to meet the rigorous demands of industrial and R&D use.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent moisture absorption, which may affect product performance.
